Hello !
(Sorry for my english)

I am currently trying to make a drag & drop in a QTreeWidget. So I put the corresponding settings and the method dropEvent :

Qt Code: 
  1. class TreeWidget : public QTreeWidget
  2. {
  3. protected:
  4.  
  5.   virtual void dropEvent(QDropEvent *event) override
  6.   {
  7.     QModelIndex index = indexAt(event->pos());
  8.     if (!index.isValid()) {  // just in case
  9.       event->setDropAction(Qt::IgnoreAction);
  10.       return;
  11.     }
  12.  
  13.     QTreeWidgetItem* item = itemFromIndex(index);
  14.     qDebug() << "drop on item" << item->text(0);
  15.  
  16.     QTreeWidget::dropEvent(event);
  17.   }
  18. };
  19.  
  20. int main()
  21. {
  22.   TreeWidget *listWidget = new TreeWidget;
  23.   listWidget->setSelectionMode(QAbstractItemView::SingleSelection);
  24.   listWidget->setDragEnabled(true);
  25.   listWidget->viewport()->setAcceptDrops(true);
  26.   listWidget->setDropIndicatorShown(true);
  27.   listWidget->setDragDropMode(QAbstractItemView::InternalMove);
  28. }
To copy to clipboard, switch view to plain text mode 

But in my case, I would like to move only parent items. In the code, I get the destination item, but how get dragged item ?

Have I to overload a drag method ? Launch the drag myself from mousePressEvent ? What is the best way to do ?

Thanks !
